NEW YORK REPLACEABLE cI-.osunn Fon an'enrrracnnsl Application filed December 31, 1927. Serial No. 243,98'6.

The invention relates to new and useful improvements in receptacles and more particularly to a receptacle having a closure at one end thereof which may be readily removed.

An object of the invention is to provide a receptacle wherein the body wall is infolded and shaped so as to provide a projecting ledge on the outer face thereof,at the lower side of which is a retaining shoulder beneath 'which the flange of the closure may be bent for securing the same to the receptacle-body.

A still further object of the invention is to provide a closure for a receptacle of the above type which is provided with a projecting portion overhanging the ledge and with ascore line on the under side of the projection adjacent the upper portion of the ledge, thus forming a tear strip which when removed will release the closure from the receptacle.

In the vdrawings forming a part of this specification Figure 1 is a side elevational view of the receptacle and closure forming the subject matter of this invention;

Fig. 2 is a `sectional view with the receptacle partly broken away, showing the rim and closure construction;

Fig. 3 is a .sectional viewle with the receptacle likewise partly broken away showing a hermetieseal in the construction shown iny Fig. 2;

Fig. 4 is a sectional View of the receptacle also partly broken away, showing a modification of theV closure construction shown in Fig. 2; j Fig. 5 is a side elevational View with the receptacle partly broken away showing the preferred tear strip; f

, Fig. 6 is a top sectional view taken on line 6--6 of Fig. 5, showing the formation of the tear strip.

The invention is directed broadly to a receptacle which is preferably cylindrical and made 'of metal. The cylindrical body hasits end portion folded inwardly and the body portion adjacentl the infolded part is shaped so as to provide an outwardly projecting ledge extending all the way around the en'd of the body portion. "Thisend of the body portion is closed by a'closure having a central depressed portion adapted to extend within the body portion and make engagement with the lnner face of the inturned portion and with the body wall beneath said inturned portion. Said closure has a llaterally projecting portion extending outwardly from the outer face of the ledge and located intermediate the upper v and lower extremes of said projecting le This projecting ledge forms a retainin shoulder and a flange on the closure is adapte to be bent underneath said shoulder for securing the closure to the receptacle body. The closure is provided with a groove or score line at the junction of the flange and the laterally projecting portion forming a tear strip which may be removed for releasing the closure from the receptacle body.

Referring more in 'detail to the drawings,

the receptacle includes a body portion l having the improved closure 3 attached to one end thereof and an ordinary end 2 double seamed to the other end thereof. The improved closure is attached to the body portion by the manufacturer and after the receptacle has beenfilled, then/the ordinary end 2 is secured thereto by the packer. The end wall of the body to which the closure 3 is attached is bent inwardly, as indicated at 5 in the drawings. This inwardly bent portion is offset so asv to p rovide a laterally projectin ledge 9 which overhangs the wall of the bo y portion 1. This provides a shoulder 4 at thevlower side of the ledge which becomes a retaining shoulder for securing the closure to the re- -A ceptacle body. The closure is provided with a central depressed portion 6 which is of sufficient extent so as to frictionally engage the inner face 7 ofthe inturned `portion of the body and also the wall 7 of the body beneath `said inturned portion.

^ The closure as shown in Figs. 1, 2 and 3 has its outer depending portion bent so as to provide a laterally projecting portion 10.

-The laterally projecting portion is disposed adjacent the lower extremity of the project- `ing ledge. Extending downwardly from this laterally extending portion is a iiange 11. The closure is provided with a groove or score line 12 between the flange and the laterally projecting portion 10 which provides in said flange a tear strip. iThe tear strip is provided with a 4tongue 13 formed by cutting the metalof the liange as indicated at 14. This serves as a means for removing the tear strip for releasing the closure from the receptacle body. The score line is at the inner edge of the metal forming the laterally projecting vportion 10. After the tear strip is removed the hand when grasping the closure to remove or replace it is kept from contact with the raw edge of metal on the closure by this projecting portion 10. Vhcn the closure is placed on lthe receptacle the flange is bent underneath the shoulder 4 into firm contact with the outer wall of the receptacle and the projecting ledge serves as the securing means for holding the closure on.

As shown in Fig. 3 of the drawings a gasket 15 is provided and this gasket is clamped zo by the fold in the metal forming the laterally projecting portion 10. It is of suliicient width so .that when the closure is placed on the receptacle the gasket will be pressed against the outer wall of the ledge and form 5 atight seal between the closure and the ledge.

In Fig. 4 of the drawings the laterally projecting portion 10 is shown as placed at the X extreme upper edge of the ledge. In Fig. 5 of the drawings, the depending flange is shown $0 as provided with vertical corrugations 16.

These corrugations aid in the removing of the tear strip as the rolling of the tear strip onto a key will insure the correct shearing of the strip as these corrugations will cause the axis of the key to remain parallel to the side wall of the receptacle. ,c

It is obvious that minor changes in the details of construction may be made without departing from the spirit of the invention as set forth in the appended claims.

I claim:

1. A receptacle comprising a. body having the end portion thereof inturned and outwardly bowed so as to form a projecting ledge providing at the under side thereof a smooth unbroken retaining shoulder, a closure for said body portion, said closure having a portion projecting beyond the ledge on the body of the receptacle and inturned inwardly to overhang the body, thereby providing an underface, and a flange depending from the projecting portion of the closure and adapted to be bent underneath the retaining shoulder making contact at the lower part of the ledge, said flange having a score line therein adjacent the underface of said projecting portion forming a tear strip which may be removedfor releasing the closure.

2.4 A receptacle comprising al body having 50 the end portion thereof inturned and outwardlybowed to form a projecting ledge providing at the under side thereof a smooth unbroken retaining shoulder, a closure having a central depression adapted to frictionally fit within 05 the body of the receptacle, said closure having a depending portion adapted to frictionally engage an outer wall of the receptacle body, said depending portion being bent so as to provide a laterally projectin portion turned inwardly to overhang the body, thereby providing an underface, and a flange depending from the projecting portion of the closure and adapted to be bent underneath said retaining shoulder 4making contact at the lower part of the ledge, said llange having a score line therein adjacent the underface of said projecting portion forming a rip strip which may be removed for releasing the closure.

In testimony whereof I affix my signature.

LEONARD BURBANK.
